Table 3 Evaluation indices of the present Study.
Statistical index | Equation | Optimal value | Equations |
|---|---|---|---|
Coefficient of determination | \(\:{R}^{2}=\frac{{\sum\:}_{i=1}^{n}({G}_{i}-\stackrel{-}{G})({P}_{i}-\stackrel{-}{P})}{\sqrt{{{\sum\:}_{i=1}^{n}\left({G}_{i}-\stackrel{-}{G}\right)}^{2}}\sqrt{{{\sum\:}_{i=1}^{n}\left({P}_{i}-P\right)}^{2}}}\) | 1 | 16. |
Root mean square error (RMSE) | \(\:RMSE=\sqrt{\frac{{\sum\:}_{i=1}^{n}{({P}_{i}-{G}_{i})}^{2}}{n}}\) | 0 | 17. |
